The quaternary ammonium salt cationic surfactant with long-chain alkyl and epoxy groups is very important intermediate product to synthesis novel functional surfactants. In this paper, a kind of quaternary ammonium salt cationic surfactant with long-chain alkyl and epoxy groups was synthesized by traditional method with epichlorohydrin and N-octadecyldimethylamine as raw materials. During the synthesis, the best reaction conditions have been obtained, that the reaction temperature is 35 °C, the reaction time is 4 h and the best mol ratio of epichlorohydrin to timethylamine is 5:1. In addition, the synthesized intermediate with long-chain alkyl and epoxy groups plays a very important roles in the development of cationic surfactant.

Quaternary Ammonium Cationic Surfactants

Quaternary ammonium cationic surfactants have very important application in the papermaking industry, which is a series of important paper softening agents. In order to obtain an environment-friendly paper softening agent, a novel diester gemini quaternary ammonium salt cationic surfactant has been prepared. Dodecyldimethyl amine, epichlorohydrin and adipic acid were used as raw materials to synthesize the surfactant, and Fourier transform infrared spectroscopy was used to characterize the groups in reaction product. Moreover, the softening effect of the diester gemini quaternary ammonium salt cationic surfactant was studied in detail.

Gemini Cationic Surfactant

In order to obtain some novel cationic surfactants with high surface activity, n-octadecyldimethylamine and epichlorohydrin were used to synthesize 2-hydroxy-1, 3-dis (chloride octadecyl dimethyl ammonium) propane, which was a kind of gemini quaternary ammonium salt. N-octadecyldimethylamine and epichlorohydrin were used to prepare active epoxy intermediate glycidyloctadecyldimethyl ammonium chlorided, and then glycidyloctadecyldimethyl ammonium chlorided was reacted with octadecyldimethyl amine hydrochloride to synthesize the gemini cationic surfactant. FTIR and 1H NMR were used to represent structure of the gemini cationic surfactant. The interface characteristics were studied in detail. The critical micellar concentration (CMC) was determined by surface tension test to obtain the values of CMC and surface tension at CMC. The foam ability and foam stability of the gemini cationic surfactant were also discussed through contrast octadecyltrimethyl ammonium chloride and cetyltrimethyl ammonium chloride.

Inhibition Performance

Two kinds of alkynoxymethyl benzyl quaternary ammonium salt (ABQAS) were synthesized by raw materials of paraformaldehyde, propiolic alcohol, organic amine, benzyl chloride and ethanol under nitrogen protection, toluene as carrying agent. The products were characterized by FTIR. According to the characteristics of blast furnace gas pipeline, quaternary ammonium salt type compound corrosion inhibitor formulas were designed, and their corrosion inhibition performance were evaluated by weight-loss method and electrochemical method. The results showed that the products were synthesized as expected, the two kinds of products had excellent inhibition performance to the cathode electrochemical process of A3 carbon steel, and the corrosion inhibition efficiency in simulative blast furnace gas reached to 100%.
